Yes, an implicit dependency. I'm not very excited about an implicit
dependency if a port depends upon this dependency directly. And
Acroread depends upon it directly.

An implicit dependency (let's call it port A) makes it "a little bit
harder" for someone who changes port A in a way which results in the
need to change all ports which depend upon it.

The point is: USE_LINUX implies some magic behind the scenes which
every linux port needs (more or less). So the current behavior is to
not strib executables when installed by install(1). If you don't use
install(1), it may not affect you (because it implies a brandelf to
FreeBSD), and if you use install(1), you will get what you want (but
only if you use USE_LINUX=yes). It also sets STRIP_CMD to the right
value (either true if the linux strip isn't available, or the linux
strip command). USE_LINUX also implies NO_FILTER_SHLIBS.

You can do all this on your own, but it would defeat the purpose of the
ports collection (and USE_LINUX).

As a general rule we can say: every linux port should use USE_LINUX.
The only exceptions are:
 - in linux_base*
 - where the use of USE_LINUX breaks the port

Both exceptions aren't met in acroread7 so far.

That's the part which brandelf changes. So strictly speaking it's
needed. It may be the case that someone can shoot into his foot without
the brandelf. But the license issue is reason enough to not brandelf
anything. But please add a comment (maybe somewhere in/between do-*)
into the makefile why the brandelf isn't done.

I've mailed the patchset (or at least the URL to it) several times (at
least 2 times I think, maybe more) to each maintainer before I
committed the large changeset.

There are several people which interpret this differently. Please have
a look at the corresponding discussion in ports at . I don't have a URL at
hand ATM... maybe one of the fellow readers can hand it out quickly?

The discussion starts at:

The initial question is about switching from plist files to
autogeneration, but it's not a lot of work to do a plist file for the
linux ports. I just did it in the morning for linux_base-8 and it was
done in a minute.

And there are already some tools which assist in generating the plist

Please have a look at the discussion.

That's kind of strange, don't you think? It should be covered by
linux_base (at least the default linux_base has such code (from you?)
already) and without linux_base acroread isn't installed. Any ideas
what could be the cause of this?
